Shimano Deore CS-M4100 10-Speed Cassette 11-42T

Precise. Lightweight. Trail-Ready.

The Shimano Deore CS-M4100 is a 10-speed Dyna-Sys cassette built for mountain bikers who want reliable, smooth shifting without the premium price tag. The 11-42T range gives you the climbing gears you need while keeping close-ratio steps in the middle for efficient pedalling on rolling terrain.

Hyperglide Shifting

Shimano's Hyperglide sprocket technology uses a computer-designed tooth profile with contoured shift gates — delivering crisp, smooth shifts even under load. Whether you're grinding up a steep climb or sprinting on the descent, gear changes stay predictable and precise.

• Close-ratio gearing for finer cadence control and more efficient energy use
• Sprockets cut away and drilled to reduce weight without sacrificing rigidity
• Compatible with Shimano HG freehub bodies
• Designed for 10-speed HG-X MTB chains
• Part of the Shimano Deore M4100 Dyna-Sys groupset
